BUNG- FOR RACKlNG-BARRELS."

SPECIFICATION forming part of Letters Patent No. 272,039, dated February13, 1883.

Application filed December 13. 1882. (No model.)

falo, in the county of Erie and State of New York, have invented certainnew and useful 5 Improvements on a Bung for Racking-Barrels,

860.; and ,I do hereby declare that the following description of my saidinvention, taken in connection -\Vll'.ll.'th6' accompanying sheet ofdrawings, forms a full, clear, and exact specification, which willenable others skilled in the art to which it appertains to make and usethe same.

a My present invention has general reference to bungsfor racking-barrelsand similar storin g-vessels for beer, ale, &c.; and it consistsessentially in the peculiar. and novel combina- 1 tion of parts anddetails of construction, as

hereinafter first fully set forth and described, and then pointed out inthe claims.

In the drawings already referred to, which illustrate my said inventionmore fully, Figure 1 is a side elevation of myimproved bung andracking-cock. Fig. 2 is a longitudinal sectional elevation of the same.Fig. 3 is aplan. Fig. 4 is a side elevation ofthe bung-expander,and'Fig. 5 is a plaii of the same.

Like parts are designated by corresponding letters of reference in allthe figures.

The object of my present invention is the production of a simple andeffective expansible bung and stop-cock combined, which can be readilyinserted into the barrels, casks,hogsheads, 850., and as readilywithdrawn therefrom as occasion requires. To attain'this resuit Iconstruct a bushing, A, of india-rubber or other similar elasticsubstanceormaterial, in the form of a hollow truncated cone inverted,its exterior size or dimensions depending upon the size of thehung-holein connection with which the bung is to be used. The upper orlargest end of this bushing is contracted at D, so as to receive anexteriorly screw-threaded band, D, and an interior locking band or book,0, the contracted part D beingarrangd to project beyond the faces of thebands B C, so as to form a packing-ring for the cap E, screwed over thescrew-threaded band B. I In this cap E is a screw-threaded aperture,through which (or rather into which) the shank F of a faucet, F, ispassed by means of itscxterior screwthread, as clearly shown in Fig. 2.Thelower end, F, of the shank F screws into a recess.

h, in the upper end, l,of a tapering plug For body, H, located in thecorrespondingly-shaped core of the bushing'A. soas to make a rigid andfixed connection with said body H.

in operation the cap E is first removed from A the bushing A and thefaucet F screwed into the cap. Now the body H is attached to the faucetF on the screw end F and the capE re; placed. The bungis then looselyinserted into the bung-hole in the stave P, after which the faucet F isscrewed downwardly so as to force the body H downward in the bushing A,thereby expanding the lat-terso much as to cause it to be tightly wedgedinto the bung-hole. Its

removal from the cask, barrel, &c., is an impossibility unless the plugHis first withdrawn from the bushing sufficiently to allow it to contractto its normal size.

0n the upper end of the faucet F is provided an external screw-thread,G, by meansof which and a suitable hose andvooupling connection may beestablished with an air-pump, an acidgenerator, or anyother-device,apparatus, ma

chine, &c., the-plug H being provided with a passage, h, forobviousreasons.

I have constructed this expanslble bun g with an especial view to itsuse in connection with the storing-tanks or hogsheads employed inbreweries for holding lager and other beer. In these tanks, &c., itoften happensthat the carbonic acid generated by or in the liquoritt.

creases in pressure a predetermined limit, and for this reason provisionmust be made for the free and unobstructed escape of the surplus gas.This is accomplished bysecuring (screwing) a safety-valve onto thescrew-threaded portion G of the faucet F. I have devised one suchapparatus, for which application for Letters Patent will be duly made,and 1 do not therefore show such devicein connection with the presentinvention, Although designedsubstituting for the faucet F a commonscrewbolt, (not shown,) by means of'which the plug H may be operatedfrom the outside of the bung.

Having thus fully described myinvention, I claim as new and desire tosecure to me by Letters Patent of the United States- 1. As a new andimproved article of manufacture, an expansiblc bung consisting of ahollow tapering elastic bushing, a cap having an internal screw-thread,a tapering plug fitting theinterior of said bushing, and a screw devicepassing through a threaded orifice in said cap to actuate said plug fromthe exterior of the bung, as and for the object specified.

2. A bung for beer and other casks,-consisting of an elastic taperingbushing having on its 'upper end an exteriorly" screwthreaded band, acap screwed to said band and provided with a screw-threaded aperture,and a threaded device, substantially as specified, passing through saidcap and actuating an expansion device within said elastic bushing,substantially as'described, for the object stated.

3. The combination, with the elastic bush- 25 in g A, having on itsupper end a screw-threaded collar, B, and a locking-band, G, of the capE, faucet F, having the screw-threaded shank F passed through a threadedorifice in said cap E and engaging with a hollow plug, H, the wholebeing constructed for operation substantially in the manner as and forthe object stated.

4. In expansible brings, the bushing A, having the contracted portion D,provided with an exterior band, B, and anvinterior 'band,'O, saidportion D projecting beyond the face of said bands and operating inconjunction with a cap, E,suhstantiall v as described and stated.

In testimony that I claim the foregoing as my invention I have heretoset my hand in the presence of two subscribing witnesses.
